同时使用两个Kinect [英] Using Two Kinect at the same time

问题描述

您好

我想同时从两个Kinect设备获取图像流，但是有问题。 第二个Kinect的初始化失败。这是一个显示问题的简单代码：

 
  // Bug_report.cpp：定义控制台应用程序的入口点。 
  //  
 #pragma一次
 
 #include " stdafx.h"  
 #include " windows.h"  
 
 #include " MSR_NuiApi。 h"  
 
 
  int  _tmain（ int  argc，_TCHAR * argv []）
 {
 
 printf（"" Connecting to Kinetics ... \ n"< /跨度>）; 
 
 HRESULT hr，hr0，hr1，hr_init_0，hr_init_1; 
  int  no_kinetics; 
 
 hr = MSR_NUIGetDeviceCount（& no_kinetics）; 
 printf（"％d Kinetics found the\\\ n"，no_kinetics）; 
 
  if （no_kinetics！= 2）{
 
 printf（"此测试需要两个动力学！中止... \ n"）; 
  return  -1; 
} 
 
 INuiInstance * kinect_0 = NULL; 
 hr_init_0 = MSR_NuiCreateInstanceByIndex（0，& kinect_0）; 
 
  if （hr_init_0 == S_OK）{
 
 printf（" Created Kinetic instance 0，pointer addres：％p \ n" ，kinect_0）; 
} 
  else  {
 
 printf（"创建Kinetic实例0 FAILED。\ n""）; 
} 
 hr0 = kinect_0-> NuiInitialize（NUI_INITIALIZE_FLAG_USES_SKELETON）; 
 
  if （hr0 == S_OK）{
 printf（" ; Kinect 0的初始化成功\\ n"）; 
} 
  else  {
 printf（"动力学初始化0失败了！返回代码是％d \ n" ，（ int ）hr0）; 
  // return -3;  
} 
 
 printf（" \\\
" ）; 
 INuiInstance * kinect_1 = NULL; 
 hr_init_1 = MSR_NuiCreateInstanceByIndex（1，& kinect_1）; 
 printf（" Created Kinetic instance 1，pointer addres：％p \ n" ，kinect_1）; 
 
 hr1 = kinect_1-> NuiInitialize（NUI_INITIALIZE_FLAG_USES_SKELETON）; 
 
  if （hr1 == S_OK）{
 printf（" ; Kinect 1的初始化成功\\ n"）; 
} 
  else  {
 printf（"动能初始化1失败了！返回代码是％d \ n" ，（ int ）hr1）; 
  // return -3;  
} 
 
  return  0; 
} 
 
 

解决方案

您好，您可以使用多个Kinect捕获 图像流同一时间。

但是，您的初始化是 第二个Kinect失败了，原因可能是 您的两个Kinect设备都连接在一个USB控制器中。   Kinect设备连接到同一USB主控制器时可能无法正常工作
。

使用多个Kinect开发应用程序时，请确保设备连接不同的USB控制器和 两者都插上外接电源。

Hello

I would like to acquire image stream from two Kinect devices at the same time, however there is a problem.  Initialization of a second Kinect fails. Here is a simple code that shows the problem:

// Bug_report.cpp : Defines the entry point for the console application.
//
#pragma once

#include "stdafx.h"
#include "windows.h"

#include "MSR_NuiApi.h"


int _tmain(int argc, _TCHAR* argv[])
{
	
	printf("Connecting to Kinetics ...\n");

	HRESULT hr, hr0, hr1, hr_init_0, hr_init_1;
	int no_kinetics;

	hr = MSR_NUIGetDeviceCount(&no_kinetics);
	printf(" %d Kinetics found \n\n", no_kinetics);
	
	if (no_kinetics != 2) {
		
		printf ("Two kinetics are needed for this test! Aborting ...\n");
		return -1 ;
	}

	INuiInstance*  kinect_0=NULL;  
	hr_init_0 = MSR_NuiCreateInstanceByIndex(0, &kinect_0);
	
	if (hr_init_0 == S_OK) {
	
		printf("Created Kinetic instance 0, pointer addres:  %p \n",kinect_0);
	}
	else {

		printf("Creation of Kinetic instance 0 FAILED. \n");
	}
	hr0 = kinect_0->NuiInitialize(NUI_INITIALIZE_FLAG_USES_SKELETON);
	
	if (hr0 == S_OK) {	
		printf("Initialization of Kinect 0 was successful\n");
	}
	else {
		printf("Initialization of kinetic 0 failed ! Return code was %d\n",(int)hr0);
		//return -3;
	}
	
	printf("\n");
	INuiInstance*  kinect_1=NULL; 
	hr_init_1 = MSR_NuiCreateInstanceByIndex(1, &kinect_1);
	printf("Created Kinetic instance 1, pointer addres:  %p \n",kinect_1);
	
	hr1 = kinect_1->NuiInitialize(NUI_INITIALIZE_FLAG_USES_SKELETON); 
	
	if (hr1 == S_OK) {	
		printf("Initialization of Kinect 1 was successful\n");
	}
	else {
		printf("Initialization of kinetic 1 failed ! Return code was %d\n",(int)hr1);
		//return -3;
	}

	return 0;
}

解决方案

Hi, You can use multiple Kinect to capture  Image Stream Same time.

However, your initialization is  second Kinect is failing because the reason could be  both of your Kinect device connected in a single USB Controller.   Kinect devices might not work reliably when they are connected to the same USB host controller .

While developing application using multiple Kinect, make sure devices are connected with different USB Controller and  both are plugged in with external power.

Just Checkout the answer in one of the forum post, http://social.msdn.microsoft.com/Forums/en-US/kinectsdk/thread/58644472-25ce-4378-aeab-424307440616/#da320604-885a-4cb0-9ad8-6ec187dec2b7

 

Here is a sample application developed using multiple kinect device

Hope this will helps !
